Authenticating with access hash instead of reseller password with cPanel API2

Hello.

I am trying to extract disk and bandwidth usage from cPanel accounts under a reseller. To this end, I am using the cPanel API2 StatsBar->stats->display. The problem I am having is authenticating. When I use the reseller password to log in to any account below the reseller, everything works fine. However, this seems like a bad solution as opposed to using access hashes. But when using the access hash of the reseller account instead (located in /home/reseller/.accesshash), I get access denied errors.

Could anyone tell me what I am doing wrong? Am I not supposed to be using access hashes here? Is the use of reseller passwords the advocated and approved solution?

Thanks a lot. My code is below.

Code:

		...
		$cpCfg = array('cpanel' => array('service' => array('cpanel' => array(
			'host' => 'ip goes here',
			'user' => 'any cPanel account goes here',
			//'password' => 'reseller password goes here'
			'accesshash' => $access-hash-without-newlines-goes-here
		))));
		$cp = Cpanel_PublicAPI::getInstance($cpCfg);
		$queryMF = array(
			'module' => 'StatsBar',
			'function' => 'stat',
		);
		$queryArgs = array(
			'display' => 'diskusage|bandwidthusage'
		);
		$response = $cp->cpanel_api2_request('cpanel', $queryMF, $queryArgs);

		echo '<pre>'.print_r($response, true).'</pre>';
